SIP trunks with BGP

[billmatthews]

We have two data centers (primary and dr). We have two SIP trunks at primary, and one at DR.

Our ITSP is suggesting we use BGP between all three cube routers. I'm not clear how that would work.

Our internal routing is OSPF, but that's unrelated to what they're talking about.  I think they mean BGP between us and the ITSP.  Why would that matter for SIP, they're just point to point links?  SIP Options handle failover.    What networks would we advertise or receive via BGP?

Thanks

Hi Bill.

As you know, BGP and OSPF are dynamic routing protocol and they are partially related to siglaning protocol.

As you correctly stated, signaling protocol such as SIP and H323 no matter how they reach the far end to establish the comminucations.

The main thing is that they are usign a stable and capable link , enough to support the service they are intended to do.

I would suggest to talk to your TSP to clarify better their point of view.
